The tension in the string corresponds to the gravitational attraction between the Sun and any planet.
Answer:
direction, speed
means the object is staying still, 0
newtons, N
the sum of all the forces acting on an object
Explanation:
Answer:
Explanation:
If a baseball is hit into the air with a velocity of 27 m/s, we want to determine the maximum height of the ball. Using the projecile formula;
Max height H = u²/2g
u is the initial velocity of the body = 27m/s
g is the acceleration due to gravity = 9.81m/s²
H = 27²/2(9.81)
H = 729/19.62
H = 37.16m
Hence the ball went 37.16m high
Answer:
Explanation:
Expression for time period of pendulum is given as follows
where l is length of pendulum and g is acceleration due to gravity .
Putting the given values for first place
Putting the values for second place
Dividing these two equation
T = 2.66455 s.
624 = 6(7x-1)
104=7x-1
105=7x
x= 15cm
